A gay eardrum that tends to only hear things that are queer or homosexual.

A person with a queerdrum usually turns normal conversations into something sexual pertaining to a dick, a penis, or an ass.
Girl: "You're not using your pick right on the E string."
Guy: "He's not using his dick right on his G-string?"
Girl: "There you go again listening from your queerdrum again.."
